Update on cross-match service

Posted by Thomas Boch on 21 November 2013 15:10 CET

In the last months, cross-identification jobs submitted to the cross-match service were suffering from hardware problems resulting in poor performances and slower computation time.

This problem is now fixed and users of the service should now experience better performances.

As an example, here is the typical execution time for various jobs:
- cross-match at 5 arcsec between a user-upload list of 100,000 positions and 2MASS : 20 seconds
- cross-match at 5 arcsec between SIMBAD (7 million objects) and GSC2.3 (900+ million objects) : 10 minutes

In addition, the maximum allowed radius has been increased to 120 arcsec.
